The Dual capsule Dragon flight system allows aerobraking, aerocapture followed by subsequent EDL for one or both Dragons some days later.

This system allows for the trunk and retracted solar arrays to survive aerobraking and to allow for the mass production of Mars Exploration Rovers (MER’s) We save the weight of MER cruise stage, Backshell/heat shield

We place three externally mounted MER’s to the Dragon that are released as weights during EDL , this means that three MER’s have landed close to one another a problem wich we will discuss shortly. On board the Dragon are two more MER’s! and a ISRU machine to allow the MER’s to be relocated further from the initial landing site by the Dragon hopping to move its MER brood.
